Spiralize the zucchinis
Cut the zucchini ends, spiralize into noodles, and break them into manageable strands. Put the zoodles in a large bowl and set aside. If you want less moisture, pat them with paper towel for a few seconds.
Make the avocado-basil sauce
Add avocados, basil, garlic, lemon juice, hemp seeds, a pinch of salt, and red pepper flakes into the food processor. Blend on high until silky and smooth. Stop and taste; add salt or lemon as needed.
Toss and serve
Pour the pesto over the zoodles and toss thoroughly so every strand gets coated. Serve immediately with extra hemp seeds or a sprinkle of nutritional yeast. Eat right away for best texture.
Pro move: If you plan to eat later, keep the sauce and zoodles separate and toss just before serving.
